Definitions
- the present invention relates to a new and improved regulator for use in controlling or modulating the pressure of supplied gases.
- Gas regulators are a staple of industry, being used in a wide variety of applications to control and maintain the pressure of gases utilized in industrial, commercial and home uses. Such regulators are typically precision devices, able to maintain relatively constant output pressures over a wide range of input pressures and environmental conditions.
- regulator repair and adjustment are typically the province of trained servicemen.
- a regulator When a regulator is in need of repair or replacement, it can represent a sizeable cost in both time and labor. Repair or replacement typically requires disconnecting the regulator, and its often associated equipment, such as flow meters, valves and the like, from the gas supply, repair or replacement of the operating mechanism, and reinstallation of the regulator and the associated equipment into the system.
- experience has shown that, because of the delicate nature of the regulator and the interplay between its components, inattention or carelessness during a repair, as well as the removal and installation processes themselves, may result in further or other damage or misadjustment to the regulator.
- Another purpose of the present invention is to provide a gas regulator in which the operating elements are in a sub-housing, while system coupling components are in another housing.
- Still a further purpose of the present invention is to provide a regulator of a modular construction in which a housing portion, in which the operating elements are located, may be easily separated and removed from another housing portion without necessity of complete disconnection from the operating system.
- Yet another purpose of the present invention is to provide a two-part regulator in which the parts are joined by a plug and socket-type connection.
- Still another purpose of the present invention is to provide a modular regulator which provides for improved means for coupling housing portions of the regulator together, irrespective of relative orientation.
- the present invention comprises a gas regulator, which may be of the spring and diaphragm type, having a regulator base in which inlets and outlets are located and which provide coupling means between the regulator and a gas system.
- the base has an aperture into which a regulator body is mounted.
- the regulator body houses the gas-controlling elements. Inlets and outlets in the base terminate at the aperture, and align with corresponding passageways in the regulator body which direct the gas flow to and from the gas controlling element.
- the base and body mate together in a plug and socket configuration, allowing the body to be removed from and replaced in the base without disconnecting the base from the gas system.
- a gasket system is employed to provide for gas-tight seals between the base and body.
- the regulator aperture base may be formed with a cylindrical inner surface, with inlets and outlets leading thereto.
- the regulator body may be formed with a mating cylindrical portion having peripheral gas entrance and exit chambers which allows the regulator body to be inserted in the base without regard for radial alignment with the inlets and outlets.
- FIG. 1 is a perspective view, partially cut away, of a modular regulator constructed in accordance with the present invention
- FIG. 2 is a top plan view in section taken along line 2--2 of FIG. 1;
- FIG. 3 is a side elevation view in section taken along line 3--3 of FIG. 1.
- a modular regulator 10 which may be used, for example, in conjunction with the supply of carbon dioxide gas for carbonated beverage dispensing, comprises regulator base 12 in which is mounted regulator body 14.
- regulator body 14 encloses and supports the gas pressure control mechanism of the regulator 10, while regulator base 12 provides an interface between the pressure control mechanism and the gas system with which the regulator 10 is employed.
- a clamp assembly 16 may be provided to retain the regulator body 14 in the base 12 and to prevent unauthorized regulator body 14 removal or tampering.
- regulator base 12 includes an aperture or cavity, preferably cylindrical, extending substantially through the base 12, surrounding and forming a socket for the regulator body 14.
- the base wall surrounding the aperture is provided with a first set of diametrically opposed inlets 18, 20, and a second pair of diametrically opposed outlets 22, 24.
- the inlets 18, 20 and outlets 22, 24 which may comprise threaded bores configured to accept couplings and connectors as known in the art, are preferably oriented perpendicularly to each other. Pairs of inlets 18, 20 and outlets 22, 24 are provided to facilitate the connection of gauges or meters on both the inlet and outlet sides of the regulator base 12 along with the gas flow connections.
- the individual inlets 18, 20 and outlets 22, 24 may be utilized or capped as required.
- the inlets 18, 20 and outlets 22, 24 are oriented in two separate horizontal planes or levels, extending through the base 12 and exiting at different levels at the socket aperture, allowing them to independently interface with inlet and outlet portions of the regulator control mechanism as explained herein.
- regulator body 14 which forms a plug-like connector with the base socket, may preferably comprise a lower body portion 26 and a bonnet 28. Mating threads 30 allow the bonnet 28 to be removably mounted upon the lower body 26.
- the lower body 26, which may be formed of aluminum or similar metal, is particularly sized and dimensioned to fit as a plug within the mating socket cavity of the regulator base 12. As seen in the Figures the lower body 26 may be cylindrical to mate with a compatible cylindrical socket aperture.
- First and second peripheral grooves or channels 32, 34 which preferably encircle the lower body 26, form an inlet and an outlet chamber, respectively, in the regulator body 14, and are positioned to align with the inlets 18, 20 and outlets 22, 24 in regulator base 12 when the regulator body 14 is fully seated therein, as may be determined by contact between a bottom surface 36 of lower body 26 and an inner ledge 38 formed in regulator base 12 serving as a stop.
- Three O-rings or gaskets 40, 42, 44 are mounted in respective peripheral receiving slots about the periphery of the lower body 26 to provide gas-tight seals between the lower body 26 and base 12, and to seal the inlet and outlet chamber grooves 32, 34.
- the gaskets 40, 42, 44 may alternatively be mounted upon the inner surface of the socket aperture in the base 12.
- the regulator body 14 With a circular cross-section for the lower body 26, and the inlet and outlet chambers extending entirely about its periphery as depicted in the Figures, the regulator body 14 may be inserted into the regulator base 12 without regard for angular orientation, as the inlets 18, 20 and outlets 22, 24 in the base 12 will always align with the associated chamber in the regulator body 14.
- alignment means may be provided to allow the body 14 to be inserted into the base 12 to align the inlets 18, 20 and outlets 22, 24 with the inlet and outlet chambers in the body 14.
- the pressure control elements of the regulator located within the regulator body 14 and covered by bonnet 28, may be as known in the art and may include a stem 46 coupled to diaphragm assembly 48.
- Stem 46 in conjunction with threaded capsule 50, defines a modulating valve assembly which passes gas from spring chamber 52, which is coupled to the peripheral inlet chamber groove 32 by inlet passageways 54, to outlet passageways 56 which are in turn connected to the peripheral outlet chamber groove 34, as seen in FIGS. 2 and 3.
- An overpressure relief valve 64 in bore 66 may be provided in the exit path for overpressure relief as known in the art.
- regulator body 14 may be easily installed in and removed from, regulator base 12 by a simple plug-like action, the regulator base 12 and body 14 forming a plug and socket-type assembly. With the regulator body 14 removed, which may be accomplished without physical uncoupling of the regulator base 12 from the gas system to which the regulator 10 is connected, the regulator body 14 itself may be readily replaced, or disassembled for repair by unthreading the bonnet 28 from the lower body 26. Because the gas enters and leaves the regulator body 14 through horizontally-directed passageways 32, 34, there are no vertical forces developed between the body 14 and base 12, thus insuring that operation of the regulator 10 will not lead to misregistration or separation of the body 14 and base 12.
- peripheral grooves or channels 32, 34 function as gas reception chambers which couple to inlets 18, 20 and outlets 22, 24 in the base 12 irrespective of relative radial orientation of the regulator body 14,
- the base 12 may similarly or alternatively be provided with similar grooves or channels upon the inner surface of the socket aperture to form peripheral gas reception chambers in the base 12. These grooves are in alignment with the grooves 32, 34.
- grooves 32, 34 may be eliminated, the inlet passageways 54 and outlet passageways 56 directly terminating at the periphery of the lower body 26 in register with the base grooves, providing gas flow to and from the body 14 irrespective of radial body alignment.
- clamp assembly 16 may be provided. As best seen in FIG. 1, clamp assembly 16 may include a forked arm 67 which lies above an exterior shoulder 68 of the bonnet 28 and which embraces the upper portion of the bonnet 28. An angled leg 70 of the clamp assembly 16 is provided with a throughbore which aligns with a vertical bore formed in a portion of the regulator base 12. A bolt 72 secures the clamp assembly 16 in place thus preventing the regulator body 14 from being separated from the base 12 without removal of the clamp assembly 16.
- the head of the bolt 72 may be provided with a particularly formed head to allow gripping and thus bolt rotation and removal only by a particularly configured tool, further preventing unauthorized disassembly. Alternatively, other clamp means may be employed.
